CourseGradeLevelCreditsRemove
Unweighted GPA3.5
Weighted GPA3.875

Scale version: US High School 4.0/5.0 (KE 1.0). Regular uses the 4.0 letter table. Honors adds 0.5 and AP/IB add 1.0, except F stays 0.

FormulaUnweighted GPA = Σ(base points × credits) ÷ credits; Weighted GPA adds +0.5 Honors or +1.0 AP/IB
Calculation steps
  1. Unweighted quality points = 14
  2. Weighted quality points = 15.5
  3. Credits = 4
  4. Unweighted GPA = 14 ÷ 4 = 3.5
  5. Weighted GPA = 15.5 ÷ 4 = 3.875

How it works

How to use this high school gpa calculator

  1. Enter each course, letter grade, level, and credit value.
  2. Leave unused rows blank or set credits to 0 to skip them.
  3. Read unweighted GPA, weighted GPA, and the stated scale version.

Formula

The calculation formula

Unweighted GPA = Σ(base points × credits) ÷ credits; Weighted GPA adds +0.5 Honors or +1.0 AP/IB
01

Convert each letter to the 4.0 table: A=4.0 through F=0.

02

For weighted GPA, add 0.5 for Honors or 1.0 for AP/IB. F stays 0.

03

Multiply by credits and divide by total credits.

Worked examples

Example calculations

Mixed levels, 1 credit each

English A Regular, Algebra B+ Honors, Biology A- AP, and History B Regular: unweighted (4 + 3.3 + 3.7 + 3) ÷ 4 = 3.5. Weighted (4 + 3.8 + 4.7 + 3) ÷ 4 = 3.875.

An F does not get AP weight

AP F and Regular A, 1 credit each, average to 2.0 on both scales because a failing grade stays 0.

When to use it

Common use cases

  • See both unweighted and weighted GPA on one transcript
  • Compare Regular, Honors, and AP course choices
  • Estimate a year GPA from credits and letter grades

Limits

Assumptions and limits

  • Scale version: US High School 4.0/5.0 (KE 1.0).
  • Letter table: A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, C-=1.7, D+=1.3, D=1.0, F=0. A+ is not a separate value.
  • Honors adds 0.5. AP and IB add 1.0. F never receives a bonus.
  • Districts differ. Some use +1.0 for Honors or a 4.3 A+. This page does not apply those local tables.
  • Blank or zero-credit rows are ignored.

Questions

Frequently asked questions

What is the difference between weighted and unweighted GPA?

Unweighted uses only the letter on a 4.0 scale. Weighted adds extra points for Honors, AP, or IB so a harder course can raise the average above 4.0.

Is this the same as the college GPA calculator?

No. The GPA Calculator is a college 4.0 semester average with no course-level bonus. Use this page when the transcript marks Regular, Honors, AP, or IB.

Why is my school’s weighted GPA different?

Many districts publish their own bonus and cap. This tool states one common convention (+0.5 Honors, +1.0 AP/IB) so the numbers can be checked. Replace the bonus if your handbook differs.
